(Cl. 160-369) or separably supporting a window screen in position on a window frame so that both inward and upward pressures are exerted on the screen frame to maintain the screen frame in tight abutting insect-excluding contact with the window frame and, at'the same time, to firmly hold the screen frame in positionwith a minimum possibility of accidental displacement or rattling thereof.

Another object is to provide a combination of a window frame and a screen frame wherein the two frames have novel and improved yieldingly separably co-acting parts for mounting and holding the screen frame in the Window frame and forpermitting'easy and quick application and removal of the screen frame to and from the window frame, respectively. I j I Still anotherobject is to provide such a combination 3,179,507 Patented Feb. 23, 19.55

The front wall ll of the window frame A is common to both the upper and lower portion, and preferably-smooth and flat, and in accordance with the invention the frame of a screen G is separably mounted on the window frame in tight insect-excluding contact with said front surface of the window frame. 1

As shown, the screen G is rectangular and of a size such that the upper rail 5 abuts the upper rail or lintel 2 of the window frame within the window opening while the lower rail 6 abuts the front face of the lower rail or sill of the window frame below the lower edge of the window opening when the screen is applied to the window frame. The stiles 7 of the screen frame connect the upper and lower rails 5 and 6 and are spaced apart a distance such as they abut the front faces of the jambs 4 of the window frame when the screen is installed. As usual, a rectangularpiece of Woven wire 8 is secured in the screen frame in known manner, the rails and stiles of the frame in the present instance having grooves 9 into which the edge portions of the woven wire mesh are bent and held by spring split tubes 16. The screen frame has some inherent resiliency and is provided on the inner side of itsupper rail'with a whereinthe upper rails of the screen frame and the window frame shall have releasable interlocking parts; and the lower rail of the screenfrarne shall have spring clips to both hold the said interlocking parts of the screenframe and the window frame in interlocked position and at the same time, to'separably co-act with the window frame to releasably interlock the lower portion of the screen frame with the window frame. I

Further, objects are to provide a simple, reliable and durable construction which can be economically manufactured; and to obtain other advantages and results that will be brought out by thefollowing suggesting description in ing portion of the window frame as shown in FIG. 3.

FIGURE 6 is a detached perspective view of one of the spring clips.

Specially describing the illustrated embodiment of the invention the reference character A designates a window frame of generally known construction which in the present instance is an extruded metal frame mounted in a window opening B in a building wall C is known manner. Within the window frame is mounted a sash of any suitable construction which in the present instance is shown as comprising an extruded metal frame D in which is mounted a pane of glass E.

The sash D is mounted in a windowopening F in the frame that extends through the front wall 1 of the window frame, the opening having an upper rail or lintel portion 2, a lower rail or sill portion 3 and side jamb portions 4.

.tion on the top rail of the screen frame and the cooperathandle loop 11. r

As shown, the lintel of the window frame has an under cut rabbet 12 at its rear side that may'be'formed by an outwardly extending depending lip 1a, and the upper rail 5 of the screen frame has a flange l3'upstanding from its top side of a length about equn "to the width of the window opening F and adapted to seat in said rabbet, be-

hind said lip. The front side of the flange 13 is inclined,

upwardly and rearwardly as shown at 13a. The lower rail '6 of the screen frame has a plurality of spring clips H secured to its underside by suitable means such as rivets 15. To prevent rotation of the clips on the'frame, the -clips have upstanding lugs or flanges '16 that are inserted in slots 17 in the rail 6. Each clip is shown as having main end portion that abuts the screen rail and through which the corresponding rivet passes, and an intermediate portion 19 disposed at right angles toportion 18. At the end of intermediate portion 19 opposite the main portion 18, the clip has a U-shaped crimp 20 which faces upwardly or toward the main portion 18 and whose arms are'spaced apart a distance slightly greater than the thickness'of wall 1 of the window frame. The arm 21'of the crimp 2h opposite the portion 19 rnerges into a curved portion 22 extending away from the portion 19 and merging into a toe portion 23' the outer extremity of .which' is bent upwardly at 24. and curved laterally at 25a. The clip is inherently resilient so that the toe, portion 23 thereof may swing relatively to the main portion 18 that is rigidly secured to screen frame and the arms of the crimp may embrace the wall 1 at the upper edge of a transverse opening 25 in the sill portion of the front wall of the window frame. The window frame also has a horizontal partition 27 extending inwardly or rearwardly of the front wall from said openings 25 as best shown in FIG. 3.

When it is desired to mount the screen in the window frame, a person standing inside the window will lift the screen through the window opening end-wise as is usually done when installing screens from the inside of a house. The screen then is turned into its upright position and inclined slightly outwardly, whereupon the clips Hare inserted through their respective openings. The screen is then pulled toward the window frame with the toe pontions of the clip resting upon-the partition 27. Thereupon, the screen is pressed downwardly against the resiliency of the spring clips by gripping handle 11, and the flange is slipped behind the lip la to the rabbet 12 as shown in FIGS. 3 and 6 after which the screen is released. The spring clips then elevate the screen to firmly hold the flange 13 in the rabbet and cause the arm 21 of each clip to frictionally bear upon inner surface of the wall 1 of the a window frame as shown in FIG. 3. The curved portion 22 and the. arm 21 of each clip, thus cooperate with the front wall l to draw the screen frame into tight abutting contact with, the face of said front Wall, and at the same time, the inclined surface 13a of the flange 13 engages the rear sideof the lip 1a to force the upper portion of the screen frame into contact with the face of the window The arms 21 and the curved portions 22 of the frame. clips, and the flange 13 of the screen frame firmly hold the frame against accidental displacement and in tight insect-excluding contact with theportions of the window frame bordering the window opening. 7 I

' The manner of removing the screen will be' obvious, the screen frame simply being pushed downwardly, to disengage the flange 13 from thelip 1a so that the frame can be tilted-outwardly aboutits bottom end, the clips principles'of the invention and that the details of the construction of the combination Window frameand' screen canbe modified and changed in the spirit and scope of the invention,

of thescreen and window frames and the constructions One, advantage of theipresent invention-is that it pro vides a simple and inexpensive mannerofattaching a which has a so-call'ed drip lip corresponding to the lip la and also has aplurality ofdrain holes corresponding to opening in the sill portion of'the window frame, said clip abutting a portion of said window frame rearwardly of said, frontr wall and exerting yielding pressure on saidv i For example, there maybe two or more flanges or lugscorresponding' to the flange 13,.and there could be one or more clips H, depending upon the sizes window-screento a known type of metal window frame the openings 25. The screen has attached thereto as a V part thereof all hardware necessary for attaching the screen to the-window frame, and there is no necessity for H drilling or otherwise modifying the extruded'metal window frame for adding screws or other fasteners orhangers. Other window frames could be provided with rabbetsilZ and openings25to cooperate'withflanges or lugs l3-and clips H on the screen frame. Y

It will also be understood by those skilled in the art that while the invention has been specifically described in connection with a window screen having a frame in which is secured a sheet of wire mesh, theinvention-also contemplates other frames having materials other than wire mesh therein; inother wordslthe invention could be embodied in storm sash whendesired. 'To avoid circumlocutron,- the term screen in the appended claims is intended to include other types of window closing panels such as storm sash; r
